Serial CMEs (May 28, 2010)

The Sun unleashed a series of four coronal mass ejections CMEs just in two-days (May 22-24, 2010) as the STEREO Ahead
spacecraft watched the action. While the Sun has not been very active over the last two years, it can still pack some
punches when it decides to. In the coronagraph images, the Sun, blocked out by an occulting disk (seen as red), is
represented by a white disk to show its relative size. CMEs are large solar storms that expel a billion tons of matter at a
million miles per hour or more.

SOHO began its Weekly Pick some time after
sending a weekly image or video clip to the American Museum of Natural
History (Rose Center) in New York City. There, the SOHO Weekly Pick is
displayed with some annotations on a large plasma display.

If your institution would also like to receive the same Weekly Pick from us
for display (usually in Photoshop or QuickTime format), please send
your inquiry to steele.hill@gsfc.nasa.gov.
